“…However, the golden-hour rule has recently been challenged [27] , [28] , [29] , with studies from both developed and developing countries indicating that prehospital time was not associated with increased mortality [30] , [31] . The opposite, however, has also been shown [32] .…”

IntroductionTrauma is a leading cause of unnatural death and disability in South Africa. The aim of the study was to determine whether method of transport, hospital arrival time or prehospital transport time intervals were associated with in-hospital mortality among trauma patients presenting to Khayelitsha Hospital, a district-level hospital on the outskirts of Cape Town, South Africa.MethodsThe Khayelitsha Hospital Emergency Centre database was retrospectively analysed for trauma-related patients presenting to the resuscitation area between 1 November 2014 and 30 April 2015. Missing data and additional variables were collected by means of a chart review. Eligible patients’ folders were scrutinised for hospital arrival time, transport time intervals, transport method and in-hospital mortality. Descriptive statistics were presented for all variables. Categorical data were analysed using the Fisher’s Exact test and Chi-square, continuous data by logistic regression and the Mann Whitney test. A confidence interval of 95% was used to describe variance and a p-value of <0.05 was deemed significant.ResultsThe majority of patients were 19–44 year old males (n = 427, 80.3%) and penetrating trauma the most frequent mechanism of injury (n = 343, 64.5%). In total, 258 (48.5%) patients arrived with their own transport, 254 (47.7%) by ambulance and 20 (3.8%) by the police service. The arrival of trauma patients peaked during the weekend, and was especially noticeable between midnight and six a.m. In-hospital mortality (n = 18, 3.4%) was not significantly affected by transport method (p = 0.26), hospital arrival time (p = 0.22) or prehospital transport time intervals (all p-values >0.09).DiscussionMethod of transport, hospital arrival time and prehospital transport time intervals did not have a substantially measurable effect on in-hospital mortality. More studies with larger samples are suggested due to the small event rate.

“…Alipour et al reported that the maximum age of people who called EMS was under 40 years [5]. Ranjbar et al reported that the average age of those who called EMS was 30 years [6]. Yadollahi et al reported that the most users of EMS were people over 60 years old [4].…”

“…Mainly the patients with internal medicine diseases or trauma at the scene of the accident call the EMS and use its services [4]. Proper functioning of the EMS with rapid and timely dispatch of ambulances and rescue forces can prevent the death of patients and their disability [5,6]. The importance of prehospital emergencies in Iran becomes more critical because Iran is one of the countries with a high mortality rate, and also, the rate of road accidents is 20 times higher than the global average [7].…”

Background: The role and function of Emergency Medical Service (EMS) in people’s health and the need for continuous evaluation of its function, especially delivering services to the patients, are essential. So, the present study was conducted to determine the time indices of prehospital emergency services in Ardabil City, Iran. Materials and Methods: This study was a retrospective cross-sectional study. Out of all calls recorded in EMS centers of Ardabil in the first 6 months of 2020, 327 calls, which resulted in the patient’s transfer to a hospital, were randomly selected. Then, the required data, including time indices and demographic information, were extracted from EMS forms filled by a medical emergency technician for each mission. The obtained data were analyzed using descriptive statistics, including mean, standard deviation, and inferential statistics, including 1-way analysis of variance and the Chi-square test in SPSS v. 22. Results: In terms of time indices, the average delay time (1.01 minutes), the response time (7.87 minutes), on-scene time (13.81 minutes), transport time (12.53 minutes), the total run time (transport time, response time, and on-scene time) (35.15 minutes), and the round trip time (52.50) had been recorded. According to the Chi-square test, there was a significant relationship between the total run time (transport time, response time, and on-scene time), transport time, round trip time, and the location of the emergency base. Conclusion: EMS time indices were at the desired level. Updating information systems, ambulances, medical equipment, and holding training courses for personnel working in this system can effectively improve time indicators.

“…Road traffic injuries have long been regarded as a ''timedependent disease.'' Hospital arrival within an hour after the injury (the so-called ''golden hour'') can improve the patient's health outcomes [1][2][3][4][5][6][7][8][9]. Currently, minimizing the time interval between traffic crashes and the provision of first professional emergency care is one of the global road safety performance targets [10].…”

“…The relationship between the prehospital time and outcome has been examined mainly in developed countries [1][2][3][4][5][6][7][8][9][19][20][21][22][23][24][25][26][27][28][29]; several studies have reported that the shorter the prehospital time, the better the outcome [30,31]. However, it remains unclear whether this finding is applicable to developing countries, especially in low-resource settings, because of the current quality of in-hospital care.…”

Background Road traffic injury has long been regarded as a “time-dependent disease.” However, shortening the prehospital time might not improve the outcome in developing countries given the current quality of in-hospital care. We aimed to examine the relationship between the prehospital time and 24-h mortality among road traffic victims in Laos. Methods A prospective observational study was conducted using the trauma registry data on traffic-injured patients who were transported by ambulance to a trauma center in the capital city of Laos from May 2018 to April 2019. The analysis focused on patients with non-mild conditions, whose outcomes could be affected by the prehospital time. To examine the relationship between a prehospital time of <60 min and 24-h mortality, a generalized estimating equation model was used incorporating the inverse probability weights utilizing the propensity score for the prehospital time. Results Of 701 patients, 73% were men, 91% were riding 2- or 3-wheel motor vehicles during the crash, and 68% had a prehospital time of <60 min. A total of 35 patients died within 24 h after the crash. Compared with those who survived, individuals who died tended to have head and torso injuries. The proportions of 24-h mortality were 4.7% and 5.4% in patients whose prehospital time was <60 min and ≥60 min, respectively. No significant relationship was found between the prehospital time and 24-h mortality. Conclusion A shorter prehospital time was not associated with the 24-h survival among road traffic victims in Laos.
